Sensors

Reed Proximity Sensors / Switches (sometimes refereed to as magnetic sensors) are inherently reliable due to their simple construction and sealed reed switch contacts.  Applications are numerous and examples of Reed Proximity Switch / Sensor applications can be found in most industries.  These sensors are not suitable for use in safety related applications.

These devices are very tolerant to misalignment and are particularly suited to environments that are contaminated by dust, dirt, grease and where non-contact interlocking or hygiene is a consideration.

Reed proximity sensors consist of two parts, the reed switch and the actuator magnet. The reed switch will change state when the actuator magnet comes into close proximity to it, there does not have to be any physical contact between the reed switch and actuator. There are up to three operating faces for both the reed switch and the actuator. The operating distance can be varied by the choice of actuator magnet.  Both the reed switches and actuator magnets are housed in rugged cases and are suitable for use in harsh environments, some of the switches are able to switch heavy loads directly. The switch configurations are available with normally open or changeover contacts.
